Junction manner of synthetic corundum and production manner null of synthetic corundum

摘要

PROBLEM TO BE SOLVED: To obtain a cell having no interference fringe on the adhered face by grinding prescribed faces for mutually adhering synthetic corundum fragments, putting the ground faces together, pressing one side thereof to form the side of the ground faces into an optically contact state, and heating the fragments at the temperature lower than the melting point to form the fragments into the wholly optical contact state. ;SOLUTION: Spacers 4 and 4, and a light transmission plate 5 are cut out from a crystalline block 1 of a synthetic corundum, and the upper and lower surfaces and one side surface of the spacers 4 and 4, and upper and lower surfaces of the light transmission plate 5 are ground. A pair of the spacers 4 and 4 are arranged on the upper surface of the light transmission plate at a distance to provide a layered product 6, and the layered product 6 is put to touch mutually crossing positioning blocks 8 and 9 on a jig table 7. One of end sides of the spacers 4 is pressed by a pressing jig 10 to form the contact surfaces of the spacers 4 and the light transmission plate 5 into an optical contact state and to form the remaining parts into a state having interference fringe on the contact surface, and the spacers 4 and the transmission plate 5 are heated to the temperature not higher than the melting point of the synthetic corundum to form the spacers 4 and the light transmission plate 5 into the optical contact state in the method for adhering the synthetic corundum.;COPYRIGHT: (C)1999,JPO
